Free phone calls using the GA628

This trick has only been reported working on PREPAID GSM CARDS and in some countries and with some sw versions.
The prepaid GSM SIM CARD is a kind of "SIM card" which only has a sertant amount of credit on it (like a normal phonebox telecard)... if it can be traced? - we don't know...

Well..here's the trick you dial the no. normally and press YES. While "connecting" is shown on the screen, the following procedure should be carried out: Press CLR then 0 then # and then NO (twice) so as to switch OFF the phone. You can then still speak on the phone while it is switched off but the SIM card does not record your calls which will lead to FREE phone calls in some countries.. we hope!!

Another variant of the code

Make a Call, while the phone says Connecting type 083# (the position 83 must be empty! ), when phone says Pos Emtpy, press the NO key and turn off the phone.

If you can make the call with the phone turned off you will face a problem when you need to hang up the phone...the only way for you to do that is remove the battery...???
